In this study, the collaborative visualization-based learning system, named semantic diagram tool is proposed as a driver to transform the classroom ecosystem. To investigate its effectiveness, two cases integrated with semantic diagram tool were designed, implemented, and analyzed. In the first case, the flow of interaction between teacher and students under the mediation of semantic diagram tool was investigated, with discourse analysis from the classroom video. In the second case, the flow of interaction between students in group under the mediation of semantic diagram tool was investigated, with the analysis of group discourse data. It is found that semantic diagram tool can make classroom more student-centered and changes the role of teacher from knowledge transfer to learning facilitator. It also can make group learners engaged more into cognitive-demanding learning activity than the situation without the integration of semantic diagram tool. Based on these findings, future researches such as teacher development and the design of learning technology are discussed.
